Try this:
grayScaleImage = zeros(ceil(max(y)), ceil(max(x)), 'uint8'); % Initialize to all zeros.
for c = 1 : length(x)
col = int32(x(c));
if col < 1
col = 1;
end
for r = 1 : length(y)
row = int32(y(r));
if row < 1
row = 1;
end
grayScaleImage(row, col) = 255; % or whatever value you want.
end
end
Assumes x and y go from 1 to some positive number. If x and y can be negative, you'll have to adjust the code.
